Mandatory helmets have since been introduced for batsmen, wicket keepers and close fielders.

The review released by Cricket Australia this morning, which looked at the causes and circumstances leading up to the death of Hughes, found new protective equipment would have been unlikely to prevent the tragedy, however.

“I do not believe that the new helmet would have afforded additional protection against the blow given the location of where Phillip was struck, as the protection to the neck, at the rear, is no different (to the helmet Hughes was wearing),” said barrister David Curtain, who chaired the review.
